SiS GO Isotonic Energy Variety Pack, 2 Fl Oz (Pack of 6)

Discovered SIS gels in the UK, in the early days of lockdown as I got back into hiking. Brought some back to the states and my son who does way more hard core hikes than me also loves them. Really seems to help on longer (over 10 mile) hikes and 30 mile plus bike rides. Some flavors better than others - wish I could get the blackcurrant in the US. Really dislike the vanilla, and personally don't care much for fruit punch and cherry flavors generally. Citrus and apple flavors are great, happy they're available in this assortment.

I will be the first admit these are a little different. A little slimy without a strong flavor. Being twice the size and thinner in texture than your typical Gu/Clif product, they take up more space, but go down easy. No reaching for water, as they almost slide their way down, as if lubricated. Their taste is somewhat neutral - you get more of a flavor hint than an explosion of taste. Definitely not sweet and sticky. I've used them for training, but would probably go for more traditional gels in a marathon due to size and weight. Six of these in my shorts would likely get me a wardrobe malfunctions and a DQ. If you're gel curious, grab some and see what they're all about.

As a group fitness instructor, I rely heavily on energy supplements. I teach on average 2-3 1 hour classes back to back of intense cardio or weight classes. I recently tried these energy gels and found them to definitely give me that extra boost that I would need before walking into the next class. I only scored it 4 out of 5 because of the amount needed to consume. Unlike other products, these servings are rather large. It is quite hard to swallow, but following it with water it is very easy to digest. Unlike other products, these energy gels are not as gooey, more a thick consistency. Flavors are ok, next time I purchase I would just select one flavor. I really liked the orange taste.

I bought these gels initially because I discovered about the "Wall" you get in marathon/training running. Around Mile 15 one day, I noticed I was getting tired quickly, and within half a mile I could not even jog, and had to sit down every minute or two of walking. A quick google search explained that I ran out of carbohydrates for energy, and my body initiated the backup (and incredibly inefficient) process of converting fat to energy. So doing some research around Energy Gels, I found out it's quite the complicated process. You need to consider the fact that during marathon's your stomach's blood supply is lessened as your body redirects more blood towards your legs. Therefore not using water (for most) or using too much can led to GI side effects or the embarrassment and awful sensation of vomiting.So after discovering this Gel company, and the fact that they're formulated so you don't need water to chug these down with, I gave the variety pack a go with training. Now I think all energy Gels flavors are not ideal, but honestly these are fine and all I need to have is something that I can not think about it. And I found the tropical one to be the "best". The last thing I need during my marathon is to consume something disgusting 3 times an hour for a few hours. So as long as it's satisfactory, like some of these were, then it's good with me.Anyways, these proved to work! I bought a box of 30 Tropical (as well as their sodium and some caffeine ones) and have used them every weekend for a few weeks now. I did a 20 mile run consuming 3 per hour per the instructions, which led me to complete my distance without any energy issues! No "wall"! These also rip fairly easily at the perforation, I had no issues with opening them during the runs.The only real issues I had with them is their size and price. It was decently larger than I thought at 6in by 2in wide, but I guess that's what 2oz gets you. A pack of 6 variety was $10, and a pack of 30 Tropical flavor was around $30, so in bulk it's a dollar a piece. I'm no expert in this field, and that may be a great deal for all I know, so take those negative opinions with a grain of salt from this newbie marathon runner.Aside from that, gonna stick with these for the long run (I promise that pun was not intentional hahaha). I will be taking them alongside me for the upcoming marathon! That alone should prove their efficacy, and hopefully your decision if you were as lost as I was in this world of energy gels.---Update:Ran the LA Marathon, carried these for a packet per 20 minutes. I had ZERO energy issues throughout the race. Sure I was tired, but I had no carbohydrate energy issues. These were also gently on my stomach with how sensitive it was that day. Strongly recommended!

This product exceeds my expectations. I was formerly active in triathlons and half Ironman races but took some time off to reprioritize. After a few years of being away from training I decided at age 61 to start training again for my next half Ironman event. I found the SIS GO product online and though I'd try it. I can't believe the boost I get from these gels. They taste better than expected, and they're not thick and hard to swallow like other gels I tried in the past. I just ordered 3 more boxes.

While the product inside each pouch is excellent and provides a great boost during long rides, the pouches are nearly impossible to open while cycling. I have resorted to precutting the top slightly with scissors prior to riding and even then they are very difficult to open. First the material is too slippery for sweaty hands and even if you use your teeth, it is very hard to open and too slippery. It is also bad for your teeth to do this. Virtually every other product on the market for this sue is easier to open, the best being the Cliff gels for opening but the product inside is not as good on those. Fix the packaging and this jumps to a 5, as is, it is almost too difficult to use while riding.

I Can't necessarily compare this product to any other gels as this is the only kind I have tried so far,But did two runs with them, a 21 Miler and a 26.2, the first was with minimal water and had zero gastric issues and still felt like my legs had energy in them when my body zonked (lack of water this time, not nutrients). and performed even better on the 26.2. I consumed 3 during the run at 50min intervals and did great. Flavors are easy enough to get down and the liquid isn't so thick that you cant squeeze it down. Overall would suggest for others looking for atleast an isotonic gel.
